Obama Aims for a Global Consensus

The Obama administration takes a crack at forging consensus on how to fight climate change, when the State Department hosts the "Major Economies Forum on Energy and Climate" this week in Washington.

The meeting, called for by President Barack Obama last month, seeks to reinvigorate a process that began under George W. Bush but that was seen by much of the world as lacking credibility because of Mr. Bush's refusal to support economy-wide curbs on U.S. greenhouse-gas emissions.
